User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:80.0) Gecko/20100101 Firefox/80.0

Steps to reproduce:

• install a new tab page extension, e.g. https://addons.mozilla.org/en-US/firefox/addon/tab-notes/?src=search
• (that extension, incidentally, was broken by 79 or 80 too. notes no longer update. i actually forked this extension so if anyone has any insights on how i might update it for 80 i'd love to know)
• open a new tab with ctrl+t or by clicking the new tab button

Actual results:

• focus goes to the notes page, not the urlbar. like i said i'm using a fork that was working fine until i updated firefox to 80 so it's clearly a change to firefox

Expected results:

• focus should go to the urlbar, or there should be an about:config toggle to control this behavior. i'm convinced this is not intentional because if i uninstall the new tab page extension, focus goes to the urlbar like it used to.

Can confirm, I have the same issue. This issue was already filed under bug 1651372. May I suggest you add your vote to that one? That way we might get it fixed sooner :)

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

update: the issue i mentioned with that tab notes extension not updating is due to https://blog.mozilla.org/addons/2020/07/09/changes-to-storage-sync-in-firefox-79/
it can be "fixed" by using storage.local instead of storage.sync. which is a shitty solution because that means it doesn't sync between profiles. seriously, 100KB limit? are people storing their browser profiles on gameboy cartridges or something? what use can a quota possibly serve that benefits the consumer? anyway you can at least ignore my question about that, or better yet take it as user/developer feedback rather than a bug report.

FYI: 1652165 looks like a dupe

Does it work correctly now?

it was probably bug 1596738

yeah, think i already commented on that bug
